**7. Recommendation for future research**

The potential for mental health to improve medical undergraduates and graduates' professionalism is also mostly unexplored. Large-scale, prospective, multicenter, and hypothesis-based or phenomenological-based qualitative studies are much needed to provide effective and generalized evidence about this issue. Both quantitative and qualitative research should be done in the future to see the long-term outcomes of the curricular change project. Support and funding for such research program are also limited, which must be alleviated. Research studies to explore the causes and consequences of medical students' distress and to examine possible solutions are not only beneficial for the affected medical student but also useful for the patients to whom they deliver their services. Subsequently, the interventions to promote students' mental health will advantage the student, the physician, the patients, and the community as a whole.
